Finding the Cost of Washers in Relation to BoltsDate: 12/8/95 at 12:46:5 From: Anonymous Subject: Word Problem Jacob Handyman has been told that 50 identical bolts and 20 identical nuts cost $9.10, whereas 30 nuts and 40 identical washers cost $4.00. If 10 each of bolts, nuts and washers cost $2.70, what is the price of each washer? Date: 5/30/96 at 11:19:41 From: Doctor Alex Subject: Re: Word Problem You will have to formulate 3 equations and solve them simultaneously to get your answer. Let bolts be b, nuts be n and washers be w. From the first statement, 50b + 20n = $9.10 Similarly from the next statements, 30n + 40w = $4.00 I would like you to try to formulate the last equation as practice, okay? The answer should be 4 cents. -Doctor Alex, The Math Forum |
